Temperature sensors are broadly used for industrial control, heating and cooling applications. One particular type of temperature sensor, NTC thermistors, have a wide range of applications thanks to their high accuracy and fast response time. TH349J39GBSN is a thermistor manufactured by Panasonic, and is suitable for use in industrial, automotive, and consumer electronics applications. This article will provide a detailed overview of the application field and working principle of TH349J39GBSN NTC thermistors.

What is an NTC Thermistor?

A thermistor is a type of temperature sensor that contains a material that changes resistance in relation to temperature changes. It works by sensing a change in temperature and responding by changing the amount of current flowing through it. NTC thermistors are negative temperature coefficient (NTC) thermistors. This means that as the temperature increases, the electrical resistance decreases. NTC thermistors are mainly used to measure and regulate temperatures in systems with a moderate degree of accuracy.

Application Field

The TH349J39GBSN NTC thermistor is ideal for a variety of applications in industrial, automotive, and consumer electronics. It is often used as a temperature sensor in HVAC systems, thermostats, temperature controls, and refrigerators. It can also be used in solar cells, LED lighting, power supplies, automotive electronics, and medical devices. Its high accuracy and fast response time make it well suited for these kinds of applications. The thermistor also features a corrosion-resistant construction which makes it suitable for outdoor use.

Working Principle and Calibration

The working principle of the TH349J39GBSN is based on the fact that its electrical resistance varies with temperature. This means that when the temperature changes, the amount of current flowing through the device is affected. In general, the resistance of the TH349J39GBSN will decrease as the temperature increases. To ensure accurate temperature measurements, the device must be calibrated for the specific temperature range being monitored.

The calibration process begins by measuring the resistance of the device at a specific temperature. This is done using a multimeter or other appropriate measuring device. Once the resistance has been measured, the desired temperature range is calculated using a thermistor calculation chart and the device is programmed accordingly. This ensures that the device can accurately measure within the specified temperature range.

Conclusion

The TH349J39GBSN is a highly accurate, fast responding NTC thermistor from Panasonic. It is used in a wide variety of applications, including industrial, automotive, and consumer electronics. In order to ensure accurate temperature measurements, the device must be calibrated for the specific temperature range being monitored.
